Expawn 

The term for a chess piece that was once, but no longer is a pawn.

Example: A queen obtained through pawn promotion, would be an expawn

"So expawn really is a valid scrabble word" said the formerly skeptical board game player.

PS2 Expansion Bay Hiding Spot 

On a PS2 (the fat model) there is an empty slot in the back meant to put in a hard drive and network adapter, this empty spot can be accessed by taking off the network adapter or cover on the back. This is a great place to hide stuff like your weed, cigarettes/cigars, cans of snuff, small flasks, money and electronic devices etc. It's a great hiding spot because nobody will think to look for anything strange in there(just make sure to close up the back after) and no one will suspect a thing!

Person 1:"I need to hide this herb somewhere for a bit!"
Person 2:"Put it in my PS2"
Person 1:"How the fuck would i do that?"
Person 2: -opens the back- "See?'
Person 1:"ABSOLUTELY PERFECT!!!"
Person 2:"Yeah the good ol' PS2 expansion bay hiding spot trick!"

expand dong 

To edit the text in an image and rearrange the letters to spell a nonsensical and often sexually suggestive/explicit phrase. Similar to the recurring gag that appears in the children’s book series “Captain Underpants”, but more risqué. The original “Expand Dong” was morphed from text found on the box cover of Donkey Kong 64.

sbubby is a variant of Expand Dong that focuses on corporate logos.

That “Thicc Mints” image is one of the best examples of expand dong that I’ve ever seen.

Hyper expansion 

A weird ass fetish were the artist draws tits that takes up most of Earth or a dick the size of Jupiter. Then, they slap any fictional character and call it "art" because the artist is so fucking lazy. Come on, if you're going to draw big tits or cock, at least don't make it take up the entire picture

Dude 1: Dude, I just found this hyper expansion picture of Amy Rose here. She's got tits the size of the fucking sun
Dude 2: What site was it posted on?
Dude 1: furaffinty.net
Dude 2: Because of course it is
